Power Electronics Tutorial

Power Electronics Tutorial

Power Electronics refers to an interdisciplinary subject within electrical engineering that deals with the design, control and conversion of power in its electric form. A system that converts electric energy to an electric load through a control circuit is known as a Power Electronic System.

The purpose of this tutorial is to introduce and explain the main concepts in Power Electronics, which include Power Semi-Conductor Devices, Phase-Controlled Converters, DC to DC Converter, Inverters and AC to AC Converters.


The target of this tutorial is electrical engineering students. It is a good resource to help them gain knowledge on electronics and circuits as applied in power electronics.


This tutorial is meant for novice readers. Almost anyone with a basic knowledge of electronics can make the most of this tutorial. It is difficult to avoid complex mathematics at some places, although we have tried to keep it at a minimum level. Therefore it is expected that the readers are comfortable with mathematical equations.
